A few questions for a not-so-novice smiter

Ok, I've been playing around with my lv 78 smiter and I have a few questions.

1. Since my merc is using "Pride" can my Concentration aura stack with his?
2. I'm currently using Enigma. Any better armor other than Arkaine? Skill+'s win with Smiters.
3. What is the "best" jewel/runes to put in my Shield and Helm? I have 32 res and I'm thinking Um's for res.

Anyway, I've kinda been messing around and I don't die ever unless It's a unique Gloam pack with a PI+Manaburn unique. That is the only thing that required me to use potions. >.> I was kinda discouraged...

Do +skills really make that much of a difference? I would think that Guillame's face would be much better...

I don't think conc can stack but you shouldn't have to worry about that. Fanaticism gets your more damage (plus the speed) and using Reaper's rather than Pride will net both you and your merc way more damage.

Actually, skill +'s are nice for Holy Shield for more damage. I'll switch to Guillaume's and Forti when I get home, sorb isn't my favorite thing... if I do it'd be Wisp for lsorb b/c Gloams are beasts... Even with nice res... And what would I put inplace of skillers? They are nice but what is "better"?
